Abstract
Abstract A waterproof construction of a wire for a motor vehicle, which wire has one or more strands and an insulating coating surrounding the strands and is connected to a nonwatertight terminal including a terminal fixed directly to a body of the motor vehicle and a terminal mounted on a nonwatertight connector, wherein at a portion of the wire between its location connected to the nonwatertight terminal and a first branch point, the insulating coating is removed from the wire so as to expose the strands and waterproof material is filled among the strands such that an insulating and waterproofing coating member is wound around an outer periphery of the waterproof material.
